Abstract (en)
[origin: WO2021069277A1] The invention relates to a molding composition containing polyetheramide (PEBA) based on a subunit 1 made of at least one linear aliphatic diamine having 15 C atoms and at least one linear aliphatic or aromatic dicarboxylic acid having 6 to 14 C atoms. Furthermore, the PEA also contains a subunit 2 made of at least one polyether diamine having at least 2,3 C-5 atoms per ether oxygen and NH2 groups at the chain ends. The moulding composition contains a maximum of 2.5% by weight of a rubber containing functional groups. The number of C atoms of at least one component of subunit 1 selected from diamine and dicarboxylic acid is at least 13 and the average molar mass number of subunit 2 is between 200 to 900 g/mol. A moulded object can be created from the moulding compound, said object can be a moulded part, a film, a bristle, a fiber or a foam.
